445 Cube Windsor Engine Brass Core

2. Lykins preps the block for the build by finishing all machine work (settling on a 0.0038- to 0.0040-inch piston to wall clearance and a 9.490 deck height), installing brass core plugs and screw-in oil gallery plugs. You can also see the Petersen dry-sump adapter on the block’s filter pad and nice hex-plugs for the block’s coolant drains. A fresh coat of high-temp black paint finishes off the block nicely.
